If grandiose and intimidating is your idea of a good time, look no further. Both are exemplified here with the Leviathan Giant Inflatable Dildo. Your plaything will be ultimately challenged with the length and girth as it stands, let alone once it is inflated. Semi-realistic bumps and ridges are added for stimulation. Lube will be necessary, as will patience. Once inserted, Leviathan can be inflated to a fuller size by pumping the attached bulb. To deflate, simply turn the knob at the base of the pump.
